我昨天遇到了软件 Raid 的问题，其中一个磁盘必须更换。我使用以下方法从阵列中删除了分区
mdadm /dev/mdx -r /dev/sdbx
在托管中心更换了故障驱动器后，我将分区表应用到了新磁盘（sdb 是坏设备）
sgdisk -R /dev/sdb /dev/sda
赋予它一个新的 ID：
sgdisk -G /dev/sdb
然后我使用以下命令再次添加所有分区：
mdadm /dev/mdx -r /dev/sdbx
除了一个分区外，其他所有分区都运行顺利，这个分区在几个小时后恢复到 60% 左右。这是突袭的当前状态：
cat /proc/mdstat

我可以挂载 /dev/md5 并列出文件。但是我无法将新分区添加到阵列。
有什么方法可以修复此问题且不丢失分区上的数据？
如果没有，是否可以只格式化该单个分区，然后再次添加新驱动器？我应该对该分区进行最新备份，这样就不会有问题了。如果可能的话，我只想删除所有分区。

在我看来，问题很大程度上是由于 上的这个未恢复的读取错误造成的sda。这是镜像中唯一当前处于活动状态的一半，因此如果无法读取，就无法干净地复制sdb6并sda6重新同步镜像。
sda我注意到，自上次通过自检以来已经过去了近 10,000 小时，因此硬件故障可能也悄悄地影响了它，这似乎并不奇怪。如果你仍然可以读取/dev/md5你躲过一劫的内容，这意味着不可读的块不在文件中。备份该分区的内容，然后替换它sda，这次用相当新的光盘替换它。一切稳定后，重新制作md5设备，并从备份中恢复。
一旦您恢复此系统，请确保您至少每月或每两个月对两个驱动器cron进行一次测试，否则这正是您收到的警告，表明事情正在变得糟糕。smartctl
